IMPROVEMENT IN CATTLE-P'AUMPS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom 'it may concern:

Be it known that I, WILLIAM H. WRIGHT, ot Rochester, iny the county of Monroe, and State of New York, have invented certain new and useful Improvements in Stock-Pumps; andI do hereby declare that the tiillowing a full, clear, and exact descliption thereof, reference being lhad to the .wcompanvingI' with the well or cistern through thepipe Il, to a branch' of which latter the discharge-pipe o is also attached.

The pump-barrel is provided with atiexible diaphragm, d, operating similarly to a plunger, and sccurely attached to the` barrel by means of the flange :band suitable bolts or screws.

The. rod e is fastened to the diaphragm by suitable washers above and below, as shown, and works in guides provided upon the frame A.

The approacll-plattorm l), upon which the animal walks, is hinged at the vouter end to the li'ame A, and the inner end, directly over the center Vline ot' thc pump-barrel, to a balance table, C.

The outer end of this'table is sustained by chains or cords, j', running over pulleys p upon the uprghts a, and connected to the platform A at a point near enough tothe hinged jointn to obtain sufiicieut power to lift-'the counter-weights ofthe animal np'on l).

The -bar g, secured to the'plattin'm througlra' slot, in the end of which the plunger-rofl c passes, operates the pump by means of suitable collars or pills upon the plunger-rod.

The dischareeaiie c 1s bent n'a armer sha 1e to l l l empty into the trough l1, andl is provided at the discharge with a valve, 1', held,to its seat by a spring or other equivalent device. `A similar valve is placedV at 4the foot of the suction-pipe b,.and the chambers which contain these valves maybe made removable, for con# venience in constructing, repairing, or oleaniue.

It is obvious that the pump and frame may be. lo cated any distance away from the well, or immediately over it. as desirable. When the animal steps upon the platlorin D, the diaphragmis -pushed down, torcing the water in the barrel B up the pipe c, while the balance-weights are raised to the position shown in dotted lines by means of the chains fand pulleys p; when theV animal steps ot, the counter-weight returns the parts to their original position, tilling the pumpbarrel for another similar operation.

It will be seen that by the use of the chainsfand pulleys p, the weight of the animal acts directly upon the hunter-weight, obviating the necessity ofthe lixcd Fulcrum for the balance table, whereby the length of the apparatus is reduced much below thosein conunon use, and the manufacturer is enabled to tit up all the parts before leaving the shop, and the 'purchaser is not obligedto construct any portion of them. The pump may thus be taken apart for shipment, and quickly put up in the required location. By supporting all the. parts upon the bed A, the ent-ire apparatus may be removed at anytime by simplyr detaching the suetiolnpipe. ln the :nrangennnltof the pipes and valycs, as shown, I attain great simplicity as well as' vconvenir-mfc inthe adjustment of the parts, sineeonly one pipe-connection 'has to be made topnt the p'nmp in operation, ami the valves are easily noce ble at anytime. 1n cold clilnatesit may be desirable to drop the puinp-lmrrel B a short distance below thc surface of t-he ground, and also to wrap the deliverypipel with a noncoinhn;tor.

What I claim as my invention, and desire to secure by Lettersrlatent ol'- the 'United States, is-

1. The platform D, hinged at thc outer or approach end, and suspended at the opposite end by the chains which lass over )ulle s 1 andare conneetcdtosad 7 platform and balance table U, as herein shown and dcscribcd.

2. The arrangement of the suction-pipe b with its foot valve, and the bent delivery-pipe e, and valve fix, in combination with the pump B, platform I.,and the table O, for the purposes set forth.
